Pay-per-call verdict, compliance and security tools for AI agents — **no API keys, no accounts, no signup**. Each tool call is paid in USDC on Base via the **x402 protocol** directly from the agent's wallet ($0.001–$0.10/call), settled through the Coinbase CDP facilitator in ~2 seconds. **21 tools across four groups:** - **On-chain safety** — token safety verdicts, wallet dossiers, one-call pre-payment trust checks (sanctions + wallet + verdict), OFAC SDN screening, payment/token verification on Base. - **Finance validators** — IBAN, VAT, BIC/SWIFT, LEI, ISIN: deterministic check-digit and format validation with enrichment, plus batch validation up to 500 items. - **Web security** — TLS certificate checks, SPF/DMARC/DKIM email-spoofing posture, brand typosquat/homoglyph detection. - **Base chain data** — live gas oracle, block info, token supply and activity. Every response is **Ed25519-signed** (verify at [chainverdict.xyz/.well-known/signing-key.json](https://chainverdict.xyz/.well-known/signing-key.json)). Quality independently measured and attested daily by x402pulse. Deterministic where possible — exactly the checks language models get wrong. **Docs:** [llms.txt](https://chainverdict.xyz/llms.txt) · [OpenAPI](https://chainverdict.xyz/openapi.json) · [Website](https://chainverdict.xyz) **Example prompts:** - "Before I pay this address, run a preflight trust check on 0x…" - "Get a token safety verdict for 0x… on Base." - "Validate these 200 IBANs in one batch." - "Is example.com's email spoofable? Check SPF/DMARC."
